What Is Ecuador's Currency?
Ecuador's currency is the U.S. dollar. The old currency, known as the sucre, stopped being used in 2000. Travelers from the U.S. won't have to exchange money when visiting Ecuador. Ecuadorian coins have different symbols but are of equivalent value to U.S. coins — there are nickels, dimes, quarters, and half dollars. You may have difficulty breaking larger bills in smaller towns. If possible, bring smaller bills to rural areas.

It's more than just having a good time or visiting beautiful places (although that's absolutely a part of it!), it's about being part of a unique experience that stays with you.
